Think about it. If you live on a street in a neighborhood, how many neighbors do you know? Do your kids play with their kids? Do you have neighborhood cookouts or gatherings? Think back to the fifties or sixties when almost everyone on your street or block knew one another. Now you're lucky if you know 2 out of 10 neighbors. People don't get out and meet the neighbors anymore.
Hmmm... you just live in a sad part of the world. We have festivals in our neighborhood once a week, where we have bands play in the park here. My neighbors have cookouts for the entire neighborhood. He owns a grocery store, so he cooks whole pigs at a time. I can't remember everyone's name, or first name anyways, but I know every family in my neighborhood. I have only been in the neighborhood for six years, two years in this house. The mayor knows everyone in my neighborhood by name, but I think that is a requirement of his job, ha ha. Maybe he knows everyone in town? Not sure.
I am a fairly social guy, regardless of how much I grumble about people coming up to talk to me everytime I light my pipe up. Despite that, I find that no matter where I go, when I light up my pipe, it seems to make me more approachable or something, because it always sparks a conversation. Everyone does seem to have their nose in their phones, but I have never thought that a reason not to disturb someone with conversation. And, I always have my phone open also.
I have been on this planet for more than half a decade, and I don't find people less sociable. Actually, maybe more so.
Maybe you should pick something from your garden that you have too much of, like okra or peppers and take them to a neighbor. I usually use that as a reason to get out and talk to someone that I haven't met yet or talked to a long while. That is one of the reasons I grow okra. You always get too many to eat, and it makes a great reason to drop in on someone.
